SHOE-TUBNDTG MACHINE.

Specification of Letters Patent.

Patented May 25, 1915.

To all whom it may concern:

Be it known that I, Grouse B. GARDNER, of Haverhill, county of Essen, State of Mas sachusetts, have invented an Improvement in Shoe-Turning Machines, of which the following is a specification.

This invention relates to certain unprovements in automatic machines and more particularly to such machines having tools which are especially adapted for turning the shoe forepart.

While various devices have been reduced for turning shoes, some of which I ave myself produced, so far as I am aware these devices have never been used to a material extent, or have not been found to be sufliciently practical to answer the requirements of the trade. Flu-thermore, these devices, so far as I am aware have been operated by hand or by foot power. One of the ob ections to a machine which is operated by foot power is that the operator needs to give practically his entire attention to the parts which directly operate u n the shoe and to manipulate theshoe with his hands during the operation, so that thestrain on the shoe will be lessened to the greatest extent possible, which he cannot do if he is at the same time pressing down a treadle with the force necessary to perform the turning operation, particularly in view of the fact that'the force necessary, in most instancw, to perform the operation is quite as much as it is practicable for a. man to exert in the ordinary range of a treadle. In devices for this purpose, so far as Iam aware, the turning operation has not been accomplished without considerable strain or pull upon the upper, which is an objection, as it pulls the shoe out of shape, or stretches it where it.

ought not to be stretched,.sometimes seriously damaging the p The object of myinylentionis to provide a shoe mahilidvfith' means whereby it may be operated by power, but which may nevertheless be at all times under the direct and immediate control of the operator.

A further object is-to provide a machine for turning the forepart-of shoes, which will imitate as closely as practicable, the hand manipulation which is necessary to perform this operation, and further, which will perform this operation practically without undue strain upon the upper.

To the accomplislunent of these objects and such others as may hereinafter appear, as will be readily understood by those skilled in the art, the invention comprises the features and combinations of arts here inafter demribed and particular y pointed out in the a pended claims.

The best orm of the invention at present known to me is by the means shown in the accompanying drawing, in which,

Figure 1 is a front elevation of a turning machine made according to my invention. Figs. 2, 3, 4, 5 and 6 are side elevations thereof, showing the parts in diflerent positions.

As shown in the drawing, I provide, a

main frame 1, in which a main shaft 2 ('Figs' 2 and 12) is journaled, said shaft extending the entire width of the machine, and a shaft 3, which is journaled in the frame in the rear of and parallel to the shaft '2. A pulley 4 and gear 5 are mounted on said shaft 3, said gear being arranged in mesh with a gear 6, secured on a. sleeve 7, the latter being rotatably mounted on the shaft 2. A disk by said spring 12.

8 (Figs. 12, 14, 20 and 21), having a pair of axially extending and diametrically disposed lugs 9 mounted in the face thereof, is also mounted on the sleeve 7, said lugs having engaging faces 9' on the endsthereof, which extend obliquely rearward with relation to the direction of rotation, and face in the direction in which they are rotated by the pulley 4, see Figs. 14 and 21. In practice the number of these lugs or teeth 9 is greatly increased, two only being shown to avoid complication. A disk 10, having its hub 10 rigidly secured on the shaft 2, is arranged adjacent the disk 8, with its face out of contact with the ends of lugs 9, and a pair of angle levers 11 are pivoted at diametrically opposite points on sald hub 10 The arms 11 of said levers 11 extend longitudinally of the shaft 2 and are normally drawn toward opposite sides of the shaft by a connecting spring 12, while the opposite arms 11 extend radially adjacent the periphery of disk 10, and are normally held in a retracted position with relation thereto A pair of dogs 13 are mounted in said disk to slide perpendicularly thereto, or axially with relation to the main shaft, said dogs being respectively connected to the ends of the arms 11" and being adapted to'be moved thereby from their normal positions, in which the opposite ends thereof from said arms are-'flush with the face of said disklfl, next disk 8, into the path of moyement'of lugs -9. Said ends of said dogs are. provided with obliquely disposed faces 13' (Fig. 14) arranged oppositely to the faces 9"and at an angle which is the complement of the angle of faces 9, so that when said dogs are moved from the position of Fig; 20 to the position of 'F 21, or from the full line to the dottedline' posit-ion of Fig. 14, said faces 13' engaged by said faces 9' and said shaft-2 will be driven from the pulley 4, which, in'

a practice, is constantly driven in the direction: Ofsfllfi arrow in Fig. 2.

Thzalbgve desirfiied clutch-machAarmsml is opera ythe o owingmeans. seeve 14 (Figs. 12, 20 and 21) is splined on the shaft-2, said sleeve being provided with a conical endporti'on 14, on which the arms llf'are rest,'so that, when'said sleeve is'mov'd toward 'theclutch, said arms ll w'ilhhe moved outwardly to throw the clutcfi'lnsmheis into engagement.*A-ring 125 i? sleeve and provided witkdiametrically arranged pins 14, and a rafiiallyproieehng arm 14 (Fig. 23) is secured on the end of said sleeve opposite its=conica.l end, in position to engage, in certain positions thereof, an arm 14 (Figs. 1

and 12) mounted on the frame and having aninclined end 14. A' bell crank lever 15 (Figs. and 21) is pivoted at 15 upon the frame, said lever comprising vertically disposed forks l5", and a horizontally disposed arm 15, the upper ends of said forks being slotted to receive pins 14 on the ring 14". A treadle 16 (Figs. 2 and 23), having an integral sleeve 16, is mounted on a pivot rod 16* fixed in the frame, and an arm 17 is secured on said sleeve and is arranged to extend beneath the under side of the horizontal arm 15, in position to engage the same after the treadle has been depressed to a certain extent, see Fig. 23. A spring 18 is coiled about the sleeve 16, and one end thereof is engaged with a stationary rod 19 on the frame, and the other end thereof is extended rearwardly and rests on the upper side of the arm 15, so that said spring acts normally to hold the sleeve 14 in the withdrawn position with relation to the clutch operating levers 11, as shown in Fig. 20.

A segment 20 (Figs. 1 and 2), provided with suitably spaced ratchetteeth 20', is rigidly secured to the inner side of the disk 10, said teeth being circularly arranged with relation to the shaft 2, and a dog 21 is slidably mounted in the frame in position to engage said teeth 20', in certain positions thereof. Said dog is pivoted to the middle portion of a lever 22, which is connected to the frame by a pivot 22 at one end, see Figs. 1 and 12, and, at its opposite end, is adapted to be engaged by the upwardly extending arm 23 (Fig. 2) of a bell crank lever, pivoted at 23, the horizontal arm 23' of said lever extending over the upper end of a vertically disposed finger 2-1 rigidly mounted on the treadle 16. A spring 25 is connected to said lever 22 and to the frame, and is adapted to swingthe lever 22 toward the rear, so as toforce the dog 21 into engagement with the ratchet segment 20. A supplemental'lifting'spring 26 (Fig. 12) is connected to the treadle 16 and, acting in con junction with the spring 18, normally holds the treadlein the raised position of Fig. 2, in'which position the finger 24, acting on the lever arms 23, 23, throws the lever 22 outwardly' and thereby holds the dog 21 out of en agement with said ratchet. s best'shown in Figs 9, 10 and 11, a actuated bolt 27 is mounted on the under side of the treadle 16, and is constantly held against the side of a bracket 28,

which extends vertically at one side of the tcreadle, and a notch 28 is formed in one side of said bracket, which said bolt is adapted to enterfl'automatically, in one position of the treadle. A tripping dog 29 is pivotally mounted at 29 upon the bracket 28, and normally rests by gravity in a hori zontal position against stop pins 30, on said bracket, in which position the end of said dog next the treadle extends opposite said notch. Said dog has an engaging face at its said end, which extends obliquely outward and upward from the side of bracket 28, when in its normal position. With this arrangement, when the treadle is depressed from its normal position, shown in 1g. 9, the bolt 27 will engage the upper side of the projecting end of dog 39 and press said end downwardly, so that said bolt may enter the notch '28, as shown in Fig. 10, and hold the treadle from upward movement. on further depression of the treadle 16, said bolt 27 will he moved out of the notch 23 and will be carried past said dog 29, so that the latter by gravity returns to its former position, as shown in Fig. 11, so that, when the treadle is raised from this position, the end of said bolt 2'? will be engaged by the inclined end face of the dog 29, which will press said bolt 27 back from the bracket 28, and hold it out of engagement with the bracket until it is carried above the notch 28, thereby preventing said bolt from becoming rengaged therein.

The main shaft 2 is provided with a crank 32 (Figs. 1 and 2),formed by providing right angular bends therein, and with a crankarm 33, the angles between said cranks being slightly more than connecting rod 34 (Figs. 3, 4 and 6) is pivoted at its lower end to the crank 32 and at its upper end to an intermediate portion of a lever 35, said lever 35 being pivotally mounted at its rear end on the frame and pivotally connected at its front end to one end of a link 36. The other end of link 36 is pivoted to the lower end of a rod 37, which extends vertically through the table 1 of the machine, and is adapted to slide in a guiding boss 1" integral with the table. A forepart turning post 38 is mounted on the upper end of said rod 37, said e50st extending vertically and being provid with a corrugated roll 39, at its upper end. The rear side of said post is vertical and the front side is slightly inclined rearwardly as it extends upwardly, and is similar to the ordinary turning-post or toe-stick employed in turning shoes by hand. A link 40 is connected at its lower end to the crank 33, and at its upper end to the lower end of a second link 41, the connection between said links 40 and 41 comprising a bolt 42 mounted in the link 41 which passes through a slot 40 in the link 40, to permit a amount of lost motion therehetween. Said link 41 is forked at its upper end, and a nut 41 is pivotally mounted between the forked portions thereof. A rod 43 is threaded into said nut i1 and extends vertically therefrom through the table 1*, the upper end of said rod 43 being pivoted to one end of an arm 44, which is there by adapted to swing in a vertical lane from.

front to rear, between guiding gers 44 mounted on boss 1'. The opposite end of main is provided with a right angularly bentrportion on the extreme end of which a transversely extending clamping head l5 is pivotally mounted, said head having a leather face 46 at the opposite side thereof from the side which is pivotally connected to said arm. A friction roll 44 is mounted on the front side of the arm 44 adjacent the point at which it is connected to the link 43. The rear side of said lever i4, adjacent the end thereof which is connected to the rod 43, is adapted to rest in the peripheral groove of a roll 47 (Fig. 7), which is rotatably mounted on a shaft 47, mounted in a bracket 48, supported on the table 1 of the frame and adapted to slide in ways 48 mounted on the table, from front to rear and in the plane in which the lever 4A is adapted to swing. A link 49 is pivoted at one end to shaft 47 and at its other end to a hand lever 50 (Fig. 2), which is pivoted on a bracket 50 on the table.

A rod 51 having ears 51 at its front end, through which the shaft 47 passes, is mounted to slide in a bracket 51 fixed on the table, and a spring 52 is mounted on said rod 51 between said bracket and a shoulder formed at the base of the ears of said rod, so that said spring acts to resist rearward pressure on the roll 47, which is thereby enabled to act as a yielding fulcrum for the arm or lever ii. A pair of springs 41 (Fig. 3) are connect-ed to the upper end of link 41 and act to hold lever 44 normally in the position of Fig. 2.

A rod 53 (Figs. 2 and 6) is adjustably mounted, at its lower end, on the rod 43 and extends parallel thereto upwardly through the table, and at its upper end is provided with a sole engaging head 54, said head having a clamping face adapted to conform to the face 46 on the head 45, the head 54 also having a projection 54, which extends downwardly and rearwardly, at the lower end thereof, and a series of downwardly extending hooked-shaped teeth 54". In the normal position of the post 38 the upper end thereof is approximately at the same level or slightly below the upper end of the head 54, as shown in Fig. 2.

A crank arm 55 (F ig. 2) is connected to the shaft 2 and a link 56 is connected at one end to said arm 55, and at its other end to an intermediate portion of a lever 57 which is pivoted at. its front end on a cross bar 57. A cylinder 58 is pivotally mounted on the frame in the rear thereof and a piston-rod 59, having a piston 59' at its lower end, is adapted to reciprocate therein, said piston being pivotally connected at its upper end to the rear end of the lever 57. Said cylinder 58 is provided with any convenient means for permitting a ready ingress and restricted egress of air at its lower end, as the check valve 58 and adjustable cock 58, indicated in dotted lines in Fig. 2.

A strap 60 (Figs. 1 and 1:2) is connected at one end to a grooved pulley 61, mounted on the left hand end of the shaft 2, in position to be wound about said pulley, and at its other end to one end of a coiled spring 62, said spring being connected at its other end to the frame and the arrangement being such that when the shaft 2 is advanced said strap will be wound upon said pulley, and when said shaft is released said spring 62 may act to reverse the rotation of the shaft.

A pair of bracket arms 63 (Figs. 1 and 6) are mounted on the boss 1" and extend horizontally forward therefrom and a square holding block 64 is pivotally mounted between said arms. A supporting rod 65 (Fig. 1) passes through, and is secured in said block 61, said rod extending vertically in front of the machine and being adapted to swing in the plane of the post 38 and lever H. A pair of brackets 66 and 67 are secured on the rod 65 adjacent the upper and lower ends thereof, and a pair of operating rods 68 and 69 are mounted therein equidistant from and at each side of rod 65, and are adapted to move longitudinally and r0- tatably with relation thereto. Said rods 68 and 69 are provided with two right angular bends in the upper ends thereof, providing rearwardly extending arms 68 and 655! (Figs. 1, 18 and 19) and upwardly extending fingers 68 and 69", said fingers being slightly inclined rearwardly from the perpendicular, so that the sides thereof are approximately parallel with the sides of the post 38 adjacent and at each side of which they are located.

A pair of arms 70 and 71 (Figs. 2 to 6 and 15) are secured on the upper forked end of the link %1, and said arms extend horizontally forward and are each provided with forked ends 70, 71, between which the rods 68 and 69 respectively pas, and said rods 68 and 69 are each provided with a pair of collars 68, 68 and 69, 69 (Fig. 1) respectively, above and below said forks TO and TP, the latter being adapted to engage said collars and limit the longitudinal movement of said rods 68 and 69 with relation to said forks, while permitting the same to swin with said rod 65. A bracket 7-2 is mounted on the lower end of the rod 6-5, see Figs. 1 and 9A, and is provided with transverse ears 72 and- 72 which are adapted to engage the rear sides of the rods 68 and-69 adjacent their lower ends, and said a bracket is also provided with a groove 72,

which is adapted to receive one edge portion of a wedge-shaped cam 73 (Figs. 3, 4 and 6), the latter being arranged with its apex end down and the opposite edge portion thereof being adapted to enter the peripheral groove of a roll 7-1 (Fig. 13) 'ro tatably mounted on a crossod 74 in the frame. A link 75 is connected at its upper endto the lower end of the cam 73, and at its lower end is eccentrically connected to a wheel 76 rotatably mounted on a shaft 76 supported in a bracket "('6 on the frame, see Fig. 12. A link 77 is also eccentrically connected at its upper end to the wheel 7 6 at a point about 90 from the oint of connection of link 75 therewith, an at itslower end, to the end of an arm 78 (Figs. 2 and 23) on the treadle sleeve 16, the arts being so arranged that when the trea e 16 is depressed, drawing said arm 78 downwardly, the wheel 76 will be caused to make a partial revolution, thereby drawing down the cam 73 and causing the bracket 72 to be forced outwardly and said fin ers 68'', 69" to be swung rearwardly (see igs. 3 and 4:).

A pair of arms 7 9 and (Figs. 1 and 13) are adjustably mounted on the rods 68 and 69, respectively, adjacent the lower ends thereof, said arms being lon tudinally curved and arranged to extend d i ver tly rearward between a pair of vertical gers S1 and 82, adjustably secured on the transverse rod 74, secured to the frame. Springs Si and are respectively connected to the arm 79 and 80 and to the frame and act to hold the sides of said arms 79 and 80 constantly in engagement with the fingers S1 and 82 respectively.

A. pair of guidin fingers 86 (Fig. 1) are mounted on the rod 57, between which the rod 65 is adapted to be swung, and a spring 67 (Figs. 3 and 4) is connected to the rod 65 and to the rod 57 and acts to hold the bracket 72 constantly in engagement with the cam 73.

A bracket 38 (Figs. 1 to 6) is rigidly mounted on the front side of the post 38 and extends horizontally forward therefrom, midway between the rods 68 and 69 and a vertical rod 88 is rigidly mounted in the front end of said bracket. As shown in detail in Fig. 25, a collar 89 is adjustably mounted on said rod 88 and ahorizontal supportin rod 90 is rigidly mounted in said collar and extends rearwardly from said rod 88. A sleeve 91 is slidably mounted on the end of said rod 90 and is connected thereto by means of a pin 90 mounted in the end of the rod, said pin being located in a pair of longitudinal slots 91 in said sleeve, said pin thereby acting to hold said sleeve from rotation and limiting the sliding movement thereof on said rod. A holding plate 92 is mounted on the rear end of the sleeve 91 in a nearly vertical position, and a spring 90" is arranged on said rod 90 and sleeve91, between said collar 89 and the plate'9'2, said spring being adapted to press said plate rearwardly and the parts being so arranged that said plate will be normally held at a short distance from the post 38, as shown in Fig. '2. The plate is transversely concaved in its middle portion and longitudinally convex at its end portions, its side edges being reversely curved and ISO onvexly formed, so that the entire edge portion thereof flares away from the post 38, as shown in Figs. 18, 19 and 25.

A vertical rod 93 (Figs. 2 to 6) is mount ed to slide longitudinally in the brackets 38 and 6-3 directly in front of the post 38 and a spring catch 93- is mounted on the bracket 63 in position to engage a series of longitudinal corrugations on said rod 93 to permit the same to be locked in the various vertical positions to which it may be adjusted. A gage-plate 9% (Fig. 18) is mounted in a horizontal position on the upper end of the rod 93 and extends in close proximity to the post- 38.

A bell crank lever 95 (Figs. 1 and 12) is pivotally mounted on the frame directly above the shaft 2, said lever having a pair of vertically disposed arms 95 which are adapted to extend on opposite sides of the clutch sleeve 14, in position to engage the annular shoulder 14 on said sleeve at the end of the conical portion 14 thereof. The other arm 95" of said lever extends horizontally and is connected at its outer end to one end of a link 96 (Figs. 1 and 2), the opposite end of said link being connected to one end of a lever 97 (Figs. 1 and T) ivotally mounted on the table. A vertical y extending rod 98 is adjustably mounted in the opposite end of said lever 97, at right angles thereto, and, to provide for a convenient means for locking said rod in various positions of adjustment, said rod is provided with a longitudinal series of teeth 98, (see Figs. 16 and 17), and a thumb lever 99 is mounted on said lever 97, and is provided with a dog 99 at one end thereof, which is adapted to engage the teeth 98 of the rod 98, and aspring 99" at the other end thereof, which is adapted to hold said dog in engagement with said teeth. A series of fingers 100, of regularly increasing length, are arran ed one above the other on the uppei end of the rod 98, and are adapted to swing thereon through an arc of 90, each finger bein provided with means for holding it by 'ctional engagement in the two positions to which it may be moved, said means each comprising a spring-pressed dog 101, (see Fig. 8), mounted in a recess in the rod 98, in position to engage the bearing surface of the finger, which is provided with recesses about 90 apart, which said dog is adapted to'enter. As a finger 100 is turned from one position to the other, as indicated in Fig. 8, the dog will be pressed inwardly, thereby causing frictional resistance to said movement, which, however, is not suflicient to prevent ready movement of the finger, but is sufiicient to hold it in either position to which it; may be moved. A rod 102 is pivoted at its lower end to the lever 35 and extends upwardly through an opening in the table of snilicient size to permit said rod to be raised longitudinally and approximately vertically when said lever 35 is swung upward, said rod bein provided with a horizontally extending hnger 103 at its up or end which is arranged to extend directly eneath said fingers 100 when swung toward the front, so that when said rod 102 is forced upwardly by the upward swinging movement of the lever 35 said finger 103 will engage whichever of the fingers 100 as may have been moved in the path thereof, thereby causing said lever 97 to be moved so as to force said link 96 downwardly, and said lever 95 to be swung so as to move the clutch sleeve 14 away from the clutch, to disengage the clutch members.

The operation of the machine above de scribed 15 as follows: When the parts are in the initial position of Figs. 1 and 2, all the parts are stationary except the clutch member 8 and the intermediate mechanism, the pulley 4 being constantly driven in the direction of the arrow in Fig. 2. The first step in the turning operation of the forepart of the shoe, the heel part of which has been previously turned, is to place the shoe forepart toe downward in a vertical position between the plate 92 and the front side of the turning-post 38, with the sole against the 0st and the ball of the shoe approximate y opposite or hearing against the roll 39 in the upper end of the post.

For the purpose of enabling the shoe to be placed readily in the exact vertical position desired, when several shoes of the same size are to be turned, the gage-plate 94 is so adjusted that the toe of the shoe will rest against said plate when the shoe is in the correct position for turn' The shoe is held in this position by tie operator, with his hands, and he then depresses the treadle 16 until the spring-pressed bolt 27 enters the notch 28, as shown in Fig. 10, in which position the treadle will be held from returning This movement of the treadle causes the arm 78 to be swung downwardly and the arm 17 to be swung upwardly until it touches the under side of the bell crank lever arm 15". The downward movement of the arm 78 causes the link 77 to be drawn downwardly, which causes a partial rotation of the wheel 76, and causes the cam 73, through the medium of the link 75, to be drawn downwardly. The downward movement of the cam 73 causes the lower ends of the rod 65, 68 and 69 to be swung forwardly, so that the upper ends thereof will be swung rearwardly on the pivot block 64 as a center. This movement also causes the rods 68 and 69 to make a. partial rotation toward each other, for, as the divergently curved arms 79 and 80 are drawn forwardly by the forward swinging movement of the rods 68 and 69, they will also be swung toward each other by the stationary fingers S1 and 82 against which they are drawn. The fingers 6S and 69 are, therefore, caused to move obliquely rearward or convergently toward the sides of the post 38. The initial position of said fingers is shown in Fig. 18, in which position the sole of the shoe is held approximately flat. The formation of the arms 79 and S0 is such that the initial movement of said fingers is rearward, during which movement they engage the shoe adjacent its edges, at the opposite sides of the post, 38 and press the same rearwardly, so that the sole is bent longitudinally, or from end to end. During the further rearward movementof said fingers, they are also moved toward each other, so that they also act to press the side edge portions of the sole closely about or against the sides of the post 38, bringing the side edges of the sole in sufliciently close proximity throughout nearly the entire length of its forepart, and particularly at the widest, or ball ortion, to permit the turning operation to performed to the best advantage.

The fingers 68 and 69" are locked in this position by the treadle, which is held from rising by the bolt 27, so that the operator is then free to adjust the shoe on the turning post to the best advantage, without holding his foot on the treadle. While the shoe is held in this position, illustrated in Fig. 3, the operator then bends the heel part of the shoe rearwardly and downwardly,

over the end of the post 38, so that the sole' is bent sharply across the same, at the ball, the heel portion of the sole being swung down against the face of the head 54, and the counter portion of the shoe being passed over the lower projecting end 54 of said head. The operator then pulls downwardly on the sides of the upper, so that the ball portion of the shoe is turned and the shoe is held in the position of Fig. 4. The 0 erator then further depresses the tread]: moving it below its locked position, causing the lever 15 to be swung, so as to advance the clutch sleeve 14, moving the clutch levers 11, so that the dogs 13 are moved outwardly beyond the face of the disk 10, in which position the oblique faces thereof will be engaged by the oblique faces of the lugs 9, on the constantly rotating disk 8, so that the shaft 2 will be driven forwardly, against the action of the returning spring 62 which is stretched by the winding of the strap 60 on pulley 61, said shaft being driven at a low rate of speed, so that the operation will not be advanced any faster than is desired by the operator. In the initial position of the parts the crank 32 is held approximately in its lowest position, so that the first part of the movement of said crank practically causes nothing more than a swinging move ment of the link 34. The crank 33 is, however, held at slightly more than from the crank 32, so that the downward move ment thereof immediately causes a down ward pull on the link 40, which causes the bolt 42 to be engaged by the link 40, at the upper end of the slot 40, of said link, and continued movement of the shaft causes the links 40 and 41 to be drawn downwardly, and with them the rod 43, thereby causing a, downward pull on the front end of the lever 44. As the lever 44 rests on the roll 47, the latter will act as a fulcrum, so that the lever will be thrown forwardly until its roll 44 engages the rod 53, and the head 45 is carried into coiiperative relation with the head 54. As the heel part of the sole has been bent down over the face of the head 54, the sole will be firmly clamped between said head 54 and the head 45, as shown in Fig. 4. As said head 54 is provided with hook-shaped teeth 54" and also an outwardly bent lip 54 at its lower end, which bends out the heel seat of the sole about the lower end of the head 45, any upward or longitudinal ull on the sole will be efi'ectively resist It will be noted in this connection that the grain or outer side of the sole will be engaged by the leather face of head 45, so that no injury will be done to tligegortions of the sole which will be exp Depression of the treadle 16 to the locked position of Fig. 10, lowers the finger 24 out of engagement with the arm 23, so that the spring 25 is permitted to force the dog 21 into engagement with the ratchet segment 20, and, when the parts are moved into the position of Fig. 4, the dog 21 will have been moved into engagement with the first tooth of the segment 20. If it is desired to arrest the turning operation at this, or any other point, the treadle 16 will be raised sulficiently to permit the dogs 13 to be withdrawn from engagement with the lugs 9, so

that the shaft 2 will be disconnected from.

the driving pulley and the parts will be arrested in their advancing movement and held by the dog 21 in the position to which they are advanced. If it is desired to advance the turning operation still further the treadle is again depressed to an extent sufficient to rengage the main clutch members.

W'hen the operation is advanced beyond the position of Fig. 4, the link 34 is forced upwardly, thereby forcing the post 38 vertically upward. At the same time the clamp members 45 and 54 are drawn downwardly by the further movement of crank 33, drawing down the heel part and thereby not only effectively holding the shoe against the upward push of the post 38, as it performs its turning operation, but also acting to turn the shoe on the post. At the same time the operator may assist the operation by pulling downwardly on the flies or sides of the upper of the shoe, the operation being thus advanced as indicated in Fig. 5. It is to be noted that the back side of the clamp member 54 rests against the post 38 as it is drawn down, which thus acts as a support for the clamp, as the pull on the shoe tends to draw the clamp toward the post.

If the fingers 68', 69" were permitted to remain in the position of Fig. 4, they would interfere with, or prevent the rolling down of the upper. as the operation is continued. To obviate this diiliculty and yet enable said fingers to perform their function of holding the sole bent longitudinally until the operation is nearly finished, means are provided for lowering the fingers to a suilicient extent to permit the upper to be rolled down without permitting said fin ers to move out of engagement with the s cc forepart. This is accomplished in the following manner In the initial clamping position of Fig. 3, the upper sides of the forks 70 and 71 are in engagement with the upper collars 68 and 69 but as the link 41 is drawn down and the parts are moved to the position of Fig. 4, said forks will be moved down into engagement with the lower collars 68 and 69, the frictional engagement of the fingers 6S" and 69' being sufficient to prevent said rods 68 and 69 falling down by gravity. Further downward movement, therefore, of the link 41 will cause said rods 68 and 69 to be drawn downwardly at approximately the rate at which said clamp members 45 and 54 are drawn down, so that all possibility of interference of the fingers with the turning operation is avoided, while they will continue to hold the sole in the bent position of Fi 19. The operation is thus continued unt-i the shoe is finally turned as shown in Fig. 6. During this operation the plate 92 assists the fingers 68 and (59 in holding the forepart in the bent position of Fig. 19, and, what is more important, it prevents the toe portion of the shoe from swinging away from the post, during practically the whole operation, the tendency to swing forwardly being caused by the upward movement of the post 38, and the downward pull of the clamp on the rear portion of the sole, which motion, if permitted, would seriously interfere with, if not prevent, the turnin of the shoe. The fingers 68" and 69" an plate 92 thus perform two highly important functions, first, to bend tile sole so that it may be turned and hold it in bent position while it is being turned, and second, to hold the sole forepart close to the side of the post until the operation is nearly finished.

Before the turning operation is begun, the rod 98, in the lever 97, is adjusted vertically to correspond approximately to the size of shoe which is to be turned, that is, according to whether the shoe is a womans shoe or misses or ehildrens, and one of the arms 100 is thrown forwardly, according to the particular size of shoe which is to be turned. The combined adjustment is such that when the shoe is nearly turned the finger 103, which is constantly raised during the turning operation by the upward movement of the lever 35, will be moved into engagement with one of the fingers 100, causing the rod 98 to be drawn upwardly swinging the lever 97, so as to operate the bell crank lever 95 and throw out the main clutch, so that further progressive movement will be prevented, and all danger of the shoe being damaged by the turning post will be avoided.

It will be understood that the turning operation may be arrested at any time by merely relieving the pressure of the treadle 16 to a sufficient extent to permit the main clutch to become disengaged. The inclination of the engaging faces of the clutch dogs 9, and 13 is such that the driving force, in addition to the force of spring 12, constantly tends to force them out of engagement, so that a release of the force which holds the dogs 13 in engagement will cause practically instantaneous release of the clutch members, and thus the progressive movement of the turning devices may be stopped practically instantaneously.

The length of the ratchet segment 20 is such that the do 21 will be in engagement therewith throng out the movement of the parts from the position of Fig. 4, to the final position of Fi 6, so that if the treadle 16 is raised only 511 ciently to disengage the clutch at any intermediate position, the parts will be held in approximately the position to which they have been advanced. Thus, any return movement by spring 62, beyond the pointat which the dog 21 engages the tooth of the segment 20 which has last passed it, is prevented. It may be noted, in this connection, that the slight return movement, which almost invariably occurs before the dog 21 engages the next tooth, is of especial advantage, as it relieves the strain, placed on the shoe by the turning devices, sufficiently to permit the operator to readjust the shoe to better advantage and more easily than would be possible if the full strain were placed thereon.

When the operation is completed and the treadle is permitted to be raised to its fullest extent the finger 24 will engage the arm 23 and withdraw the dog 21, permitting the returning spring 62 to return the parts to the initial position of Fig. 2, so that the shoe may be then readily removed.

Inasmuch as, with the construction above described, the shaft 2 cannot be rotated but slightly more than onequarter of a revolution, I provide the arm 14 (Fig. 23) on the clutch sleeve 14 which is adapted to engage the inclined face 14 on the stationary arm 14, when the parts have advanced to an extent necessary to turn any shoe which would be likely to be turned upon the machine. When this engagement occurs the arm 1% will he deflected to the left, carrying with it the clutch sleeve 14, so that the main clutch will be disconnected and further advance movement of the parts will be prevented.

During the advancing movement of the parts the crank 55 will lift link 56 which will act to swing the lever 57 upwardly and draw up the piston 59 in the cylinder 58, so that, when the treadle 16 is entirely released, so that the dog 21 is withdrawn from the ratchet se ment 20, and the main clutch is disengage the speed of the return motion of the parts, which would otherwise be caused by the returning spring, will be arrested by the air resistance in said cylinder.

The hand lever 50 is provided for the purpose of drawing back the pivot roll 47 and thus permitting the clamping head 45 to swin rearwardly, so that the operator may readjust the shoe if he finds it necessary to do so during the turning operation, without making it necessary to return the parts to the initial position.

When the treadle 16 is rmitted to rise to its fullest extent, the cam 73 will be raised permitting the spring 87 to swin the rods 68 and 69 so as to withdraw the so e bending fingers from the post 38. When the fingers 68 and 69" are moved out of en agement with the shoe, the rods 68 and 69 Wlll fall of their own wei ht, so that the up 1' collars se and 69 will rengage the for 7m and 71 and be again supported thereby.

By adjusting the vertical fingers 81 and 82 toward or from each other, the limits of the path in which the fingers 63 and 69' shall more may be varied.
